Country Summary

This page presents high-level information for Solomon Islands's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Solomon Islands's country context and climate is provided following the visualizations.

The Solomon Islands are an archipelago located in the Melanesian region of the Pacific, south-east of Papua New Guinea. Considered the “Amazon of the Seas”, the country’s expansive area covers a unique range of atolls, mountains, and salt-water lagoons, and has some of the world’s richest marine diversity. Agriculture, forestry, and fishing are the mainstay of the economy, with agriculture contributing nearly 36% of gross domestic product in 2006. Land degradation and deforestation are serious concerns in the Solomon Islands, as logging is a critical source of revenue for the country. The Solomon Islands, like all Small Island Developing States (SIDS), have been identified as one of the most vulnerable to the adverse impacts of climate change. This is due in large part to the fact that the majority of the population lives within 1.5 km of the coastline. In addition, high poverty rates, excessive dependence on foreign aid, and remoteness make the Solomon Islands particularly vulnerable to climate variability and change.

The Ministry of Environment, Climate Change, Disaster Management and Meteorology (MECDM) is the coordinator and central point for climate change engagement with all development partners including the United Nations Framework Convention on Climate Change. The Solomon Islands National Climate Change Policy (2012-2017) laid out an initial pathway to integrate climate change policy into the National Development Strategy, and strengthen capacity to mitigate and adapt to the negative impacts of climate change. The Solomon Islands ratified the Paris Agreement on September 21, 2016 and its Nationally Determined Contribution can be found here
